SPKE-THROATING MACHINE.

SPECIFICATION forming' part of Letters' Patent No. 258,031, dated May 16, 1882.

Application tiled Februaryl', (No model.)

To all whom 'it may concern Be it known that we, WILLIAM H. DoANE and GEORGE W. BUGBEE, citizens of the United States, and both residing' at Cincinnati, in the county pf Hamilton and State of Ohio, have invented certain new and useful Improvements in Spoke-Throating Machines; and we do hereby declare the following to be a full, clear, and exact description of `the invention, such as will enable others skilled in the art `to which it appertains `to make anduse the same.

This invention relates to a3 machine organizedto throat spokes on. both` sides, Without reversal, by `means of two rotary cutter-heads supported in oscillatoryhangers, which, in the operation of the machine, are automatically oscillated by the spokes to adapt the form of the throats to the cross-sectional contour of the spokes, such a machine, for instance, as is described in United States Letters Patent No. 225,355, granted to W. H. Doane and Gr. W. Bugbee, March 9, A. D. 1880.

This improvement consists in the combination, with a central housing for the support of the two oscillatory cutter-head hangers, of a horizontally-revolvin g feed-carriage composed of two concentric rings, the inner one of which is made in sectionsA bolted together after they have been laterally applied to and fitted around that part of the housing` on which said inner ring is supported and turns, in consequence of which construction of the inner ring ofthe rotary feed-carriage the housing can be cast in a single piece.

It further consists in so connecting the rings of the rotary feed-carriage that the innerring must turn in unison with the outer ring.

It further consists of specially-devised gearing for driving the' rotary feed-carriage.

In order that the invention may be clearly understood, we have illustrated in the annexed drawings and will proceed to describe the best embodiment thereof al; present known to us.

Figure 1 is a plan view of so much of a machine for throating spokes as will clearly illustrate theimprovements stated in the claims at the close of this specification.

tical axial section thereof. Fig. 3 is a plan` view of the sectional inner ring and the arm Fig. 2 is a verby which itmay be connected to the outer ring of the rotary feed-carriage. Fig. 4 is a vertical axial section, illustrating a modication of the gearing for driving the rotary feedcarriage.

The same letters of reference indicate similar `parts in all the figures.

Arefers to the bed or column on the top of' i which the housing is mounted. The housinga single piece ofcasting,`preferably cylindrical-consists of tubular orl hollow trunks B and B,`connected by, a solid neck, B2.

. At the top ofthe lower trunk, B, and in a circular seat around the neck B2 of the housing, the inner ring of the circular rotary feed-carriage is fitted and supported. Thisinner ring is constructed of two semicircular sections,` O C', tting the seat around the neck of the housing, and provided with a downwardly-projecting iiauge, c, to embrace the top of trunk B. Across the division-line of these sections C C depressed seats are formed for the reception, after the sections have been iitted around the housing, of the splices c and c2, by which the sections are rigidly joined. `When thus applied the splices should be iiush with the upper surface ofthe ring. In lieu of this mode of connecting the sections of the ring other modes-such as scarlin g, for instance-f-may be used.

The outer ring, D, of the rotary feed-carriage is concentric with the inner ring. In this instance it is supported along about one-half of its circumference upon the segmental rim E2 ofthe spider E, the iiange E' ot' which is bolted to the trunk B of the housing. The outer ring, D, is constructed with an inwardly-projecting tongue, d, tted in a guideway formed by a recess in the rim E2, in which the tongue d of said ring is confined by an overlying plate or gib, E3, secured upon the rim E2 of the spider. At the side opposite to the spider the tongue d of the outer ring of the rotary feed-carriage moves in a guideway formed by a recess on the top plate, f, of the bracketF and the overlying gib j".. When the inner ring ofthe feedcarriage is to be driven by the outer ring it is `rigidly connected to the outer ring by the arm D', as shown in Figs. 1 and 4.

Each ring is provided with upwardly-projecting pins d', against which the spokes are placed to be moved along with the feed-carriage, and past the throating cutter-heads.

The arm lD' is thinner than an ordinaryspoke, but is provided with an enlargement, d2, near its outer end for the purpose of separating the oscillatory hangers, so that the knives of the cutter-heads may clear the arm when itpasses through between them.

On the under side, and all around the outer ring, D, beveled cogs d3 are formed, by means of which the required rotary motion may be imparted to the feed-carriage by a worm, G, through the intervention of the bevel-Wheel H on shaft H'. The worm is xed on a horizontal shaft mounted in bearings on a bracket, G', cast or secured on the column A. The wormshaft is somewhat nearer the center of the machine than the cogged rim of the outer ring, D,so that the bevel-wheel H stands on a slant.

'Its axis is arranged slantingly in a vertical plane parallel to a line intersecting the axis of carriage.

lfio

the worm at the angle of the pitch, as shown in Fig. 1, so that the teeth 0f bevel-wheel H may properly mesh with both the Worm and the cogged rim of the outer ring of the feed- The axle of bevel-wheel H is journaled in a-bearing on bracket F.

The worm-shaft is provided with suitable pulleys for driving it by means ol' a belt from a counter-'shaft orv line-shaft.

According to the modification shown in Fig. 4 the rotary feed-carriage is driven directly by the worm G, suitable teeth being cut on the outer ring ot the carriage to that end.

The arm D' may be dispensed with and the innerringof thefeed-carriage driven by a bevelgear, H2, on shaft H', meshing with bevelteeth'formed on the under side of the inner rin g, 'all as clearly shown in Fig. 2'.

The positions of the respective cutter-heads in the complete machine are indicated by dottedl lines in Fig. l, one being mounted on trunk B to operate on the underside of the spoke, andthe other onthe trunk B' to operate on the upper side of the spoke. Pressure-bars .adjustably mounted on the upper trunk, B',

are also used in the complete machine for holding the spokes rmly down on the rings ofthe feed-carriage where they pass the cutter-heads. As we do not propose to make claims'in this patent for any features relating to these parts it was deemed unnecessary to illustrate them.

The rim E2 of the spider for supporting the outer ring of the feed-carriage may be made an entire ring, and the gib E3 may also be an entire ring, in which case the plate fand gib f' would fall away.

Having thus described our invention, what we claim as new is- 1. The circular rotary feedcarriagey composed of connected inner and outer rings, the inner ring being made of sections,in combination with the central housing having a neck to support the inner rin g of said carriage, substantially as before set forth.

2. The combination, substantially as before set forth, of the central housing composed of an upper and a lower trunk cast in one piece with a solid connecting-neck and the circular rotary feed-carriage, of which the inner ring is ina-de of sections laterally applied to and fitted around the solid neck of the housing.

3. The combination, substantially as before set forth, of the'circular rotary feed-carriage, the central'housing having a neck to support the inner ring of the carriage, the spider for supporting the outer ring thereof, and the gib for confining said outer ring to a recess in the rim of the spider.

4. The combination, substantially as before set forth, of the inner and outer rings of the circular rotary feed-carriage, the cogs on the outer ring thereof, and the worm for driving the outer ring through an intermediate bevelwheel the axis of which lies in a vertical plane parallel to a line intersecting the axis of the' worm at the angle of the pitch.

In testimony whereof we affix our signatures in presence of two witnesses.
